So I made a simple mod of the 'I Toy piano ripple' template and used 'Auto Restart'. I set 'Piece Length' to 240 seconds, 'Auto Restart' checked, and 'Piece Rest' set to '10' (maximum) but it doesn't rest at all between pieces, just a brief 'breath' and right into the next composition?? Tempo variation is 34/55 range and no additional voices were added (such as delayed followings), it hits 99% then ignores any rest period???
